This invention relates to garment presses and particularly to the lever mechanism for supporting and actuating the movable press element.

Generally stated the invention contemplates the use of the usual frame and buck supported thereon, and a floating lever which.

is pivotally supported adjacent its lower end and which is pivoted adjacent its upper end to a head carrying yoke or lever on which the pressing head is supported. The head and the head carrying yoke are thus sustained primarily on the floating lever. The frame is provided with two guides which preferably are substantially parallel with the line of thrust between the head and buck and the head carrying yoke is rovided with two slider elements one of w 'ch is constantly confined by the guide just mentioned and the other of which, in the upward or press opening' position of the floating lever, is above the upper limit of the guides so that it may move into or out of alignment with-the guides. Preferably this second slider is located at the point of connection of the floating lever and the head-carryin yoke but this is not necessarily the case. 'fire. parts are so proportioned that the floating leverhas a relatively short travel in a direction parallel with the press ing thrust between the head and buck. This is more than sufficient to include the necesthe guide thus permitting the yoke to be swung about the lower slider to carry the head far away from the buck. This move-' ment carries the upper slider out of alignment with the guide. a

The preferred embodiment of the invention is illustrated in the accompanying drawings in which,

Figure 1 is a side elevation of the press with parts broken away to show the construction. In this view the head and head carrying yoke are shown in full lines in their completely retracted position and in dotted lines in the position they assume when drawn forward manually preparatory to the pressing operation. The plane on which the parts view certain parts are sectioned on the plane II-II of Figure 3.

Figure 3 is a rear view in elevation.

Figure 4 is a section on the line IVIV of Figure 1.

Figure 5 is a section on the line VV of Figure 1.

6 represents a cast base whose form may be varied to suit individual preference and is sufiiciently indicated in the drawings. At the rear are two spaced upright members 7. which are parallel with each other and which at their upper ends and on their outer faces are formed with parallel projecting guide members 8 and 9 of which the forward one 9 is the longer. These are spaced to leave an intervening guideway in which the sliders, here shown as rollers, travel. The frame 6 also supports the usual'table 11 and the buck 12.

Mounted in bearing bosses 13 and 14 is a shaft 15 upon which is fixed an eccentric 16. I

such diameter that they will just enter the guideway between the guides 8 and 9 and the length of the lever 17 is such that when the 'eccentric is in its highest position see Figure 1) the rollers 23 will just clear t e upper ends of the shorter guide members 8 but will.

shaft 22. On the inner side of each arm there is mounted a roller 26. Each roller 26 fills the space between a corresponding pair of guides 8 and 9 and is confined thereby in all positions of the device.

It will be observed that the rollers 23 and 26 are duplicated to balance the guiding action but so far as the mechanical movement is conerned only one roller 23 and one roller guides 8, 9 would be which the head is manually moved into reg- 26 with one pair of strictly necessary.

The shaft may be rotated to assume either of the two positions illustrated respectively in Figures 1 and 2 by any suitable.

means. However, it is preferred to perform this operation by means of a power mechanism. Thus in the example illustrated there is included a constantly running motor 28 which drives through ashaft 29 any suitable an automatic throw-out speed reducing mechanism, indicated generally by the numeral 31, applied to its housing. Many such mechanisms are known, for example those involving planetary trains with a dental clutch and a trip to disen age the clutch upon the completion of de ite movements ;in this case upon the completion of a 180. movement of the driven shaft 15. No claim of novelty is here made for this mechanism nor is any 30 limitation to any particular mechanism im plied except that it must be capable of turning the driven shaft 180 and then bringing it to rest. Q i

32 represents a rock shaft for initially engaging the clutch of the intermittent drive. 33 is an arm for actuating the shaft 32, while 35 is a pull link for connecting the arm 33 with the bell crank 36 by which the operator actuates the clutch.

ation a cam disk 37 is mounted on the shaft 15 and has two notches 38 at 180 from each other. The notches receive, in their proper positions, a roller 39 mounted on an extension of the rock arm 33. Thus once the lever 36 has been depressed to engage the clutch it cannot rise until the cam 37 has rotated When the eccentric reaches its uppermost position the upper guide rollers 23 pass clear of'the short guide 8 and the spring 19' swings the floating lever 17 to the rear, thus carrying the pressing head upward and clear of the buck, the parts assuming the position shownin 'full lines in Figure 1.

After the operator has spread the garmenton the buck 12, and is ready to press it, he grasps the handle 27 and draws the. head forward to thedotted line position in Figure 1. At this time the rollers 23 are against the guide 9 .and in position to enter the guide way between the guides 8 and 9.

' Thereupon the operator depresses the hand lever 36 which has the eflect of engaging V the drive. Shaft 15 turns 180 carrying the In order to insure the 180 cycle of operand the spring 19 swings the floating lever 17 to the rear, retracting the head to its original position. v

The invention produces. a structure in ister with the buck with the minimum of effort and in which it is automatically retracted from register with the buck upon the release of the press. The pressing motion is rectilinear. v 1

Various changes in the structure may be made and except as specified in the claims no limitation to the exact structure illustrated is implied. T

While I prefer to use the rollers 23 and 26 as the slider elements which are guided in the guideway between the guide members 8 and 9, because of their simplicity and their antifriction qualities, other types of slider might be used. As various-structures-of this sort are known to thoseskilled in the art, it is deemed unnecessary to illustrate optional structures. What is claimed is,- 1. In a garment press, the combination of a frame; a buck supported thereby; a head;

a carrier for said head; means providing a guideway parallel with the line of thrust between the head and buck;a pair of spaced.

slider elements on said carrier; one element confined in said guideway the other normally confined thereby but capable of moving into and out of alinement with said guideway, when the head is retracted from the buck; and means for shifting said carrier in a pressing direction when the second named slider is alined with said guideway.

2. In a press, the combination of a frame; a buck supported thereby; a head; a force applying member shiftably mounted in said frame; a floating lever pivoted thereto; a head carrier pivoted. on said floating lever; means forming a guideway substantially parallel with the line of pressing thrust between the buck and head; and a pair of sliders on said head carrier one constantly confined by said guideway and the other normally confined thereby but capable of movingbeyond the limit thereof in one ex- ItJrenrie position of said force applying mem- 3.
